Image editing sofiware is making it possible for us as microscopists to digitally prepare our micrographs for output as working prints, figures for journals, slides, inclusion in reports, or as files for transmission via the Internet or World Wide Web. In the course of becoming familiar with various sofiware applications, I decided to have some fun colorizing and recombining some scanning electron micrographs. While this kind of frivolity has no place in the presentation of scientific data, learning to manipulate images in this silly way serves two purposes; both to bring humor into the steep learning curve, and to highlight the sobering fact that you can no longer believe what you see in print. Although we would all hate to admit it, there may be unscrupulous scientists in our midst, tempted to alter visual data to suit their needs. Having said that, let me now show you one way it can be done...!

The Zygaenidae are a family of day-flying moths with an unusual biology – they are capable of releasing prussic (hydrocyanic) acid. All Australian species belong to the subfamily Procridinae (commonly known as foresters) and many of these feature iridescent green colours or a wasp-like look. This is the first study of the Australian fauna of these attractive and biologically interesting moths. In this volume their beauty is captured larger-than-life in 114 finely detailed portraits by acclaimed artist František Gregor, setting a new benchmark for moth illustrations. Comprehensive general chapters discuss zygaenid morphology, biology, phylogeny and classification, with considerable new information of world-wide relevance. The book then provides in-depth treatments of the 10 genera and 43 species present in Australia, including 4 genera and 21 species new to science. It features keys to genera and species, photos of genitalia of both sexes and other diagnostic structures, and distribution maps for all species. Additionally, there are 8 pages of colour photographs and over 400 photos of microscopic structures, including more than a hundred spectacular scanning electron micrographs.

Bromodesmus catrionae n. gen., n. sp. (type species), B. militaris n. sp., B. riparius n. sp. and B. rufus n. sp. are described. The new genus is characterized by greatly reduced paranota and a gonopod telopodite expanded at the distal end into a posteriorly concave hood fringed with teeth; the hood partly protects a long, curved, acutely pointed solenomerite. Male leg setation in the type species of six Tasmanian dalodesmid genera is briefly discussed and illustrated with scanning electron micrographs. The sphaerotrichome shaft is sharply pointed in Atrophotergum; gently tapered in Dasystigma, Lissodesmus and Tasmanodesmus; expanded at the tip in Bromodesmus; and entirely absent in Gasterogramma. Tips of the setae forming the dense ventral brush on male podomeres are gently tapered in Dasystigma and Lissodesmus, truncated in Gasterogramma, expanded in Bromodesmus and forked in Tasmanodesmus.

<span>Public libraries were early adopters of Internet-based technologies and have provided public access to the Internet and computers since the early 1990s. The landscape of public-access Internet and computing was substantially different in the 1990s as the World Wide Web was only in its initial development. At that time, public libraries essentially experimented with publicaccess Internet and computer services, largely absorbing this service into existing service and resource provision without substantial consideration of the management, facilities, staffing, and other implications of public-access technology (PAT) services and resources. This article explores the implications for public libraries of the provision of PAT and seeks to look further to review issues and practices associated with PAT provision resources. While much research focuses on the amount of public access that </span><span>public libraries provide, little offers a view of the effect of public access on libraries. This article provides insights into some of the costs, issues, and challenges associated with public access and concludes with recommendations that require continued exploration.</span>

Scanning electron-micrographs have shown the covering of microvilli on the surface of the redia of Parorchis acanthus. In the contracted state the elongated microvilli with bulbous extremities seen in the surface grooves may be the result of compression. The surface of the epidermis of the cercaria is smooth on a large area of the ventral surface and lattice-like with microvilli, laterally, anteriorly, dorsally and on the tail. The spines on the body can be withdrawn into sheaths by the contraction of muscle fibres inserted into the basement lamina below each spine.I would like to express my sincere gratitude to Dr I. ap Gwynn of this department for preparing the scanning electron-micrographs and the School of Engineering Science, University of North Wales, Bangor for the use of their stereoscan. I should also like to thank Mr M. C. Bibby for technical assistance and Professor E. G. Gray and Dr W. Sinclair for assistance with the transmission electron-micrographs.

AbstractWe present new information on the parasitoids (Hymenoptera: Braconidae: Aphidiinae) of aphids infesting cotton, tobacco, citrus, and cereal agroecosystems in southeastern Europe. Nineteen species are keyed and illustrated with scanning electron micrographs and line drawings. The aphidiines presented in this work have been identified from 18 aphid taxa. Furthermore, 96 original parasitoid–aphid–plant associations are presented. Cotton, tobacco, and citrus agroecosystems are connected through aphids and their parasitoids, whereas cereal agroecosystems represent a separate group of associations.

Although Aphidiinae parasitoids have been used as agents for biocontrol of alfalfa aphids for more than half a century and have been the subject of numerous ecological investigations, there is an evident lack of systematic studies on the parasitoids of aphids infesting alfalfa in Europe. Here we present an original and up-dated key for identification of both native and invasive Aphidiinae parasitoids attacking aphids that feed on alfalfa in Europe. In total, 20 species are keyed and illustrated with scanning electron micrographs and line drawings.

In this experiment, pyrophyllite as the main materials used the flame photometer to measure adsorption. Using the qualitative analysis of the samples of XRD with internal structure and found that pyrophyllite used in the experiment as a natural mineral, the presence with other minerals. Meanwhile, scanning electron micrographs (SEM) from the display showed that the effect of pyrophyllite adsorption for cations should be more significant. Therefore, this experiment focused on the time, Na+ concentration, on the pyrophyllite and different pyrophyllite concentrations (adsorbent dosage) effect on the adsorption, in addition to the adsorption dynamics. The results showed that pyrophyllite adsorption sodium in the best time of equilibrium was 20 minutes, the concentration of NaCl was 50 mg/L, pH = 7, temperature was 313 K, the concentration of pyrophyllite was 5 mg/L.

ABSTRACTIn many tropical countries coconut (coir) fiber production is a major source of income for rural communities. The Caribbean has an abundance of coconuts but research into utilizing its by-products is limited. Environmentally friendly coir fibers are natural polymers generally discarded as waste material in this region. Research has shown that coir fiber from other parts of the world has successfully been recycled. This paper therefore investigates the mechanical properties of Caribbean coir fiber for potential applications in civil engineering.Approximately four hundred fibers were randomly taken from a coir fiber stack and subjected to retting in both distilled and saline water media. The mechanical properties of both the retted and unretted coir fibers were evaluated at weekly increments for a period of 3 months. Tensile strength test, x-ray diffraction analysis and scanning electron micrographs were used to assess trends and relationships between fiber gauge lengths, diameter, tensile strength and Young’s modulus. Diameters ranged between 0.11 mm-0.46 mm, while fiber samples were no longer than 250 mm in length. The tensile strength and strain at break decreased as the gauge length increased for both unretted and retted fibers. The opposite occurred for the relationship between the gauge length and Young’s modulus. Additionally, the tensile strength and modulus decreased as the fiber diameter increased. Neither distilled nor saline water improved the coir fiber’s crystalline index. Scanning electron micrographs qualitatively assessed fiber surfaces and captured necking and microfibril degradation at the fractured ends.The analysis revealed that the tensile strength, modulus, strain at break and crystallinity properties of the Caribbean coir fibers were comparable to commercially available coir fiber which are currently being used in many building applications.
